Application led July 7, 1902. Serial No. 114,569. (No model.)

T0 all whom it may concern.:

Be it known that we, EDWIN NORTON, residing in New York, in the countyof New York and State of New York, andVJOHN G. HODGSON, residinginChicago, in the county Of Cook and State of Illinois, citizens of theUnited States, have invented a new and useful ImprovementinaCombinedVacunmizing and Double-Seaming Machine, of which the following is aspecification.

This invention relates to can sealing and seaming machines.

The object of the invention is to produce a machine of a simple,efficient,` and durable construction by means of which cans or vesselsmay be automatically, rapidly, and cheaply vacuumized, hermeticallysealed, and their covers double-seamed thereon.

The invention consists in the means employed to accomplish this objector resultthat is to say, it consists'in the combination with a vacuumchamber or receiver to exhaust the air from the can and its contents, aseaming mechanism for seaming the cover on the can, and a carrier forconveying the cans from the receiver to the seaming mechanism.

It further consists in the combination with a series of receivers forsimultaneous operation upon a plurality of cans with a series ofdouble-seaming mechanisms for simultaneously seaming a plurality ofcans, and a carrier having a series of can-holders for. conveying aplurality of cans from the series of receivers to the series of seamingmechanisms.

It further consists in the novel construction of parts and devices andin the novel combinations of parts and devices herein shown ordescribed. i

The accompanying drawings, forming a part of this specification, showthe preferred construction of machine embodying the invention.

Fig.21 is adetail view showing 'a portion of the can and the seam formed bythe machine. Figs. 22, 23, 24. are detail views of the iexible shaft foroperating the seaming-tool holders. Fig. 25 is a detail plan view ot"the air and exhaust valve. Fig. 2b' is a section on the line 26 26 ofFig. 25. I In the drawings, A represents the frame 8o of the machine.

B B are a series of vacuum chambers or receivers,the same beingpreferably bell-shaped or having open lower ends b and adapted to moveup and down or reciprocate vertically.

C C are a series of seaming-tool holders, each preferably provided witha set of three double-seaming tools or rollers c, and preferably with aplurality of such sets of double seaming tools. 9o

D is the can-carrier, by which the cans are conveyed successively' fromthe series of receivers B to the series of seamers C, the same beingpreferably an endless 'flexible carrier or chain.

Each of the receivers B is furnished with an independently-reciprocatinghollow platen F inside the same for evenly seating the cover @c on thecan or vessel 0c and for softening the packing x2, which is interposedbetween the IcoA seaming-llanges v3 x1 on the can and cover to insurethe proper hermetic sealing and securing of the cover on and to the canby the vacu- .um or atmospheric-pressure seal, which serves to keep thecan herrnetically sealed and the cover in place thereon while it isbeing conveyed by the can-carrier from the receiver to thedouble-seaming machine.

The receivers B are reciprocated up and down on suitable guides b' onthe frame of the machine by means of the crank-disk g on the receiveroperating shaft G through the eonnecting-linksg, which are furnishedwith adjusting-turnlmckles g2 to adjust the movement. To facilitate thereciprocating Inovement of the receivers, counterbalances G' areprovided, which are connected to the receivers by chains G2, passingover pulleys G3.

The reciprocating platens F inside the receivers are independentlyreciprocated as re-I quired by cams 7L on the cam-shaft H through theconnecting-linkfand rock-shaftf, having arms f2, connecting with thestems f3 of the platens F by means of adjustable collars f4.

The can-carrier D is furnished with a series of can holders or disks D',each provided with a rubber or elastic sealing ring or pad D2, by meansof which the lower end of the receiver B is closed when it is moved downagainst the can-holder D to surround and inclose the can. Each of thecan-holders D' is also furnished with an ejector-disk D3, which isadapted to reciprocate slightly in the holder, and thus lift the can outof the counter-sink d, with which the holder is provided, to receive andregister the can with the upper chuck K while the can is being operatedupon by the seaming-tools c in the toolholder C.

The can-holders D' are mounted to rotate on the carrier D and areprovided each with a spindle or stud D4, fitting in a suitable socket orbearing D5 in the carrier, ball-bearings c7 d2 being interposed to causethe holders to rotate freely.

D15 is a track or guide for supporting the endless HeXible carrier D,theV saine heilig preferably formed integrally with the frame A on oneside and in a separate piece from the frame A on the other side of themachine for convenience in casting, and Dj D7 are the pulleys orsprocket-wheels at the opposite ends of the machine for the endlessfiexible carrier, the same being secured to vertical shafts D8 D. Theshaft D8 is jonrnaled in suitable bearings D10 on the frame of themachine and is intermittently rotated as required to move the carrierthe distance necessary to bring a number of cans one under each of thereceivers B and another set of cans in position for being operated uponby the seainers C C by any suitable connecting mechanism. The carrier islocked in position to cause the can-holders to properly register withthe receivers and with the seamers `by a movable lock D11, engaging alock wheel or disk D12. The shaft D9 of the other pulley orsprocket-wheel D7 is journaled on a slide D12, which is moved byadjusting screws D14 as may be required to take up the slack in thecarrier.

To keep the endless flexible carrierD propceivers being located on oneside of the machine and the seamers ou the opposite side thereof. Twelvecans are thus vacuumized at once, while twelve other cans are beingseamed.

The upper chuck-disks K, which cooperate with the rotatable can holdersor disks D on the carrier D to rotate the cans while they are beingoperated upon by the seaming-tools or seamers, are mounted to bothrotate and reciprocate and are furnished each with a can-ejector diskK', the stem K2 of which has a spring Ks for retracting it. The hollowshafts or spindles 7a of the rotating and reciprocating chuck-disks Kare rotated as required through the bevel-gears 7c' thereon,

which mesh with bevel-gears 7a2 on the shaft 7a2, which have bevel-gears7a4 meshing with bevel-gears 795 on the chuck-driving shaft k, which hasa driving-pulley 7137. The hollow shaft 7s of the chuck K isreciprocated as required by means of a cam 7L on the camshaft H throughthe connecting-link 7a2 and rock-shaft la", having arms k1@ connectingthrough the adjustable collars 7c11 7012 7.213 with the hollow chuckspindle or shaft 7c, a ballbearing 7614 being interposed to permit thechuck-spindle 7c to revolve freely.

The operating-rod 7.915 for the ejector-disk K' is reciprocated asrequired by arms 7.315 on the rock-shaft 7017 and connecting with saidstem 7515 through the adjustable collars 751B, said rock-shaft beingoperated by a cam h2 on the cam-shaft H through the connectinglink 7511.

Each of the seamiug-tool holders C is preferably mounted to rotate inorder to bring each seaming tool or roller c c' c2 successively intooperation against the scathing-flanges of the rotating can. The shaft Cof each toolholder is furnished with a worm-gear C2, which meshes withthe worm'C44 on the Wormshaft C4.

The shaft C' of each of the tool-holders C is mounted orjournaled on anindependentlyadjustable slide C5, carried on the laterallyadjustable barC, secured to vertically-adjustable slides C7. Theindependently-adjustable slides C5 are each adjusted as required tobring the seaming tools or rollers on the tool-holders C with therequired pressure against the scathing-Hanges of the can by means of theadjusting-screws C8. The

IIO

laterally-adj ustable bar C, carrying the slide C5, is adjustedlaterally as required to adapt the machine for operation upon cans ofdifferent diameters by means of the adjustingscrews O10, furnished withbevel-gears C11, which mesh With bevel-gears C12, splined to the uprightshaft C13, having bevel-gears C14 meshing with bevel-gears C15 on theshaft C15, having a hand-wheel C17 for effecting this adjustment.

The bar O5 is adjusted up and down as required to adapt the machine tooperate upon cans of different heights by means of the adjusting-screwsC15, operating upon the slide C7, and furnished with bevel-gears C19,which mesh with bevel-gears C20 on the shaft C21, having hand-wheels C22for effecting the vertical adjustment of the seamers.

To enable the Worm-shaft C4 to permit of individual adjustment of theseaming-toolholder slide C5 Without interfering with the proper meshingof its Worm C11 with the Worm-4 gears C2, the shaft C1 is made flexibleor furnished with jointed or flexible couplings C23 C24 C25, the blocksC24 and C25 being free to move, andthus permit the necessarylongitudinal and transverse movements of the separate sectionsor jointsof the shaft.

To arrest or quickly stop the can-holders D after the seaming operationis completed, brakes M are provided, which are adapted to engage therotating can-holders D and arrest their rotation. These brakes M arefurnished with springs m and are mounted on a rockshaft M, operated by acam h on the camshaft H through the connecting-lin ks M2 andoperating-arms M5.

N is the air-exhaust pipe, leading to any suitable exhaust mechanism,preferably a vacuum-pump N. Connecting with the exhaust-pipe N throughthe valve .N2 are a series of exhaust-pipes b5, leading to each of thereceivers, for exhausting the air therefrom. The Valve-box N3 has anair-inlet N4, which is opened by the movement of the valve to admit airto the receivers after the covers have been seated on the cans to sealthe same thereto by atmospheric pressure. Y The valve N2 isautomatically operated as required by means of a cam h on the cam-shaftH through a connecting-link n, which is furnished with a turnbuckle nfor adjusting the same.

N5 is a vacuum-gage indicating the degree or extent of vacuum produced.in the receivers.

N6 is au exhaust-gage for indicating. eX- haust-pressure in thepressure-reservoir.

To ease the reciprocating movement of the chuck-disks K, the same arefurnished witha counterbalance K1,connected thereto through thelever K5and link K5. i

The cans are automatically discharged from the holders D of the carrierD after being vacuumized and seamed by means of a dis-- being secured tothe vertically-adjustable` bracket R2, mounted on a laterally-adjustablebracket R5, which carries the dischargerail R.

To insure the reseating of the can-ejector disks D3,a movablepressure-roller S is mounted in the path of the can-holders D, so as toautomatically press down the ejector-disks D3 as the carrier moves underthe pressureroller. This pressure-roller is mounted on a crank-arm S andis actuated by a spring S2.

The stem d7 of the ejector-disk D3 is actuated to raise the ejector-diskand lift the can out of the countersink d in the rubber or elasticsealing-pad D2 by means of an inclined or raised portion C19 in thetrack D5 of the carrier D.

To hermetically close the opening in the stem of the can-holder D',through which ,the stem CF of the ejector-disk DS passes at the time thecan-holder coperates with the receiver to close the lower end thereof,the block or packing d8, of rubber or other elastic material, isinserted in the hollow stem 0f the holder D and surrounds the stem C17of the ejector Dsand is compressed by a sliding block d10,which isoperated by the inclined or raised portion d of the track D5 of thecarrier D. 4
